COLLAPSIBLE EXTENSION -STAN11 Specification of Letters Patent.

Patented Aug. 14, 1917.

Application filed Dctober 30, 1916. Serial No. 128,447.

.Y mno, a citizen of the United States, residrio ing at Los Angeles, in the county of Los Angeles, State of California, have invented new and useful Improvements in Collapsible Extension-Stands, of which the following is a specification.

This invention relates to stands for restaurant trays, tables and the like; and it is a particular object of this invention to provide a simple collapsible stand which may be folded into a minimum space; and whichl may be adjustably extended so as to provide for restaurant trays, table tops, etc., of different lengths. It is also a particular object of this invention to provide a stand suitable for general use, and particularly suitable for automobile parties, etc.

My stand is preferably made in such a manner that the two pairs of legs may be folded separately by releasing the braces eX- tending between the two sets of legs. These braces are also made so as `to be extensible tc vary the length of the stand for different sizes of trays, different lengths of table tops, etc.

My invention will be best understood from the following detailed description of a preferred form, reference being had to the accompanying drawings; in which, Figure 1 is an end elevation of the stand; Fig. 2 isa side elevation of the stand provided with a top; Fig. 3 is a plan of the stand; Fig. 4 is an enlarged detail section taken as indicated on line 44 of Fig. 2; 5 is an enlarged detail section taken as r indicated by line 5-5 on Fig. 3; Fig. 6 is an enlarged view taken as indicated by line 6 6 on Fig. 1; Fig. 7 is a side view of the parts shown in Fig. 6; Fig. 8 is an enlarged section showing the method of attachment of the top to the stand; and Fig. 9 is a view similar to Fig. 6 showing a modiication.

In the drawings I illustrate two pair of legs, each pair comprising a leg 10 and a leg 11, the legs 10 being inside and the legs 11 being outside in each instance, and each leg 10 of one pair being parallel to a leg 11 of the other pair. These legs are pivoted together at 12. The legs 11 have pivoted to their upper ends at 13 the cross members 14; and these cross members 14 rest at their other ends upon parts 15 at the upper ends of legs 10, the yparts 15 being formed by bending out the Vianges of the legs 10 at their upper ends, the parts 15 then occupying the positions shown in the drawings. An upwardly projecting pin 16 is carried by each part 15; and an aperture 17,- in cross member 14, engages around this pin. The table top 20, which may be of any suitable construction, lies upon the member 14 and is grooved at 21 to engage over the flanges of the members 14, as is particularly shown in Fig. 8. The members 14 are provided with lips 22 bent out of their Hanges, and holes 22n are drilled for screws 23, or any other suitable fastening, to hold the top 2O rigidly and permanently upon the stand it so desired.

The legs 10 and 11 and cross members 14 are all preferably made of angle bars of comparatively small size and light weight. Each set of legs may be folded by merely releasing the connection of member 14 at the pin 16, and then folding the upper ends of the legs downwardly and folding the :member 14 downwardly. The member 14 then nests directly in the leg 11, while the legll lies along the leg 10; each set of folded legs forming a compact bundle whose length is only approximately that of one of the legs. And the thickness and width of such a` bundle of two pair of legs is one and three quarters inches as a maximum.

I provide suitable adjustably eXtensible braces connected between the pairs of legs `for holding` them in their proper' relative positions. These braces may be placed between the legs in any suitable manner and direction; but I prefer to place them as illustrated in the drawings. In the drawings I show the braces placed diagonally between the pairs of legs; but they may be placed at smaller or greater angles, or may be placed horizontally across between the pairs of legs.

Each brace is preferably made of two parts and 81; the part 31 telescoping within the part 30 and a set screw 32 being provided for holding the brace adjusted to any desired length. The upper end of each brace (the upper end of each part 30) vis connected at 33 to the upper part of a leg 10 in the manner shown particularly in Fig. 4, the part 30 being turned at a right angle and passed through the fiange of the leg and then headed as shown at 34; or any other suitable means is used for attaching the brace to the leg 10 in such a manner that it may swing pivotally' in the directions indicated in Fig. 2, so as to be folded up against the leg lO'when the stand is collapsed. Each brace is permanently connected pivotally with a leg l0; but each brace is preferably detachably connected with leg 11, at the lower part of the leg, in the manner particularly shown in Figs. 6 and 7. The end of part 31 is turned at an angle as shown at 35, and a thinned portion is provided at 36 where the part 31 is passed through notch 37 ine the liange of the leg. This thinned portion iits the notch 3T in the manner shown so that the part 31 is prevented from longitudinal movement with reien ence to the leg. Then the stand is collapsed the part 3l is removed from notch 37 the braces are folded each against the leg 10= to which they are attached, and the pairs of legs are then folded in the manner hereinbefore described. If desired, the part 31 may be connected with leg 11 by havingan eye 38 upon its end which engages intwo notches 39 in. the flange of the leg 11, the eye surrounding a part 4.0 of the flange of the leg. This Jform of connection gives a more or less pivotalconnection ofl part 31 with leg l1.

I find my stand particularly useful for automobile and camping parties and the like; and in one form", I make the stand of such a height as to provide for use by persons sitting upon a low camping stool or upon the running board of an automobile; the stand being, in this form, lower than usual table height. Then my stand is folded its complete length is onlyA approximately the length of one of the legs, which is about thirty-six inches; and the folded bundle is thus easily placed in an automobile or upon its rlmning board. For these purposes I also make the top of few fiat boards hinged together, so as to fold'4 into a liat bundle which may be conveniently placed upon the running board of an automobile.l In this form of the table, allowing use ci the running board as a seat, the carrying of camp stools is obviated; especially' where the table is placed between two machines and the running boards afford seats along opposite sides of the table.

Having described a preferred form of my invention, I claim:

1-. A device of the character described,

comprising two pairs of legs, the legs of each pair being pivotally connected, a cross member pivotally attached to the upper end o one leg and detachably connected to the upper end of the other leg, the legs and cross members being made of anglebars, the means for detachably connecting the cross member to the upper end of said leg embodying a portion oi' the flange of said leg bent outwardly to a horizontal position, an upwardly projecting pin in said portion, and said cross member having an apertu-re adapted to surround the pin when the cross member rests upon said portion ;f a pair of braces connected between the pairs of legs, said braces being pivotally attached each to one leg of each pair so as to be foldable against that leg, means to detachably n connect each brace with a leg of the opposite pair, said means embodying a notch in said'leg, and hook portions at the end of each lbrace adapted to enter said notch.l

2. A device of' the character described, comprising two pairs of legs, the legs of each' pair beingl pivotally connected, a cross member pivotal-ly attached to the upper end of one leg and d etachabl-y connected to the upper endA of the other leg, the legs and cross member being made ofangle bars, the means for detachablyconnecting the `cross member to the uppery end-- of said leg embodying a portion 'of the Ela-nge of' said leg bent outwardfly` to a horizontal position, an upwardly prcjecting-v pin on 'said' portion, and said crossfmember havingan aperture adapted to surround the pin when theV cross -member rests upon said portion,4 a pair of braces connected between the pairs of legs; said braces being pivotally attached each to one leg oteach' pair so as to be oldable against that leg, meansv to detachably connect each brace with a leg of the opposite pair, saidl means embodying a notch in said leg, and hook portion at the end of the said notch, and eachv WILLIAM HUGH sin-earn.
